Greetings, and welcome to the Alkermes’ fourth quarter 2022 financial results conference call . My name is Rob, and I'll be your operator for today's call. All participant lines will be placed on mute to prevent background noise. If you should require operator assistance during the call, please press star zero on your telephone keypad. Please note that this conference is being recorded. I'll now turn the call over to Sandra Coombs, Senior Vice President of Investor Relations and Corporate Affairs. Sandy, you may now begin.
Thank you. Good morning. Welcome to the Alkermes plc conference call to discuss our financial results and business update for the quarter and year ended December 31, 2022. With me today are Richard Pops, our CEO, Iain Brown, our CFO, and Todd Nichols, our Chief Commercial Officer. Before we begin, I encourage everyone to go to the investor section of alkermes.com to find our press release, related financial tables, and reconciliations of the GAAP to non-GAAP financial measures that we'll discuss today. We believe the non-GAAP financial results in conjunction with GAAP results are useful in understanding the ongoing economics of our business. Our discussions during this conference call will include forward-looking statements. Actual results could differ materially from these forward-looking statements.
Please see slide 2 of the accompanying presentation, our press release issued this morning, and our most recent annual and quarterly reports filed with the SEC for important risk factors that could cause our actual results to differ materially from those expressed or implied in the forward-looking statements. We undertake no obligation to update or revise the information provided on this call or in the accompanying presentation as a result of new information or future results or developments. After our prepared remarks, we'll open the call for Q&A, and now I'll turn the call over to Todd.
Great. Thank you, and good morning, everyone. 2022 was a breakthrough year for our commercial organization. We achieved record sales and double-digit growth compared to the prior year for our portfolio of proprietary products driven by execution of our focused commercial strategy. The year was highlighted by the ongoing launch of LYBALVI. In its first full year of commercial launch, we exceeded expectations and delivered strong results that began to establish LYBALVI's important place in the treatment paradigm. LYBALVI's early launch success underscores the leverage we can realize across our commercial platform, which gives us a distinctive position in the neuroscience space. We launched LYBALVI just over a year ago with a broad differentiated label that includes both schizophrenia and bipolar I disorder. In its first full year, LYBALVI generated net sales of $96 million, which we believe provides a strong foundation for future growth.
In the fourth quarter, LYBALVI sales were $34.9 million, up 29% sequentially, driven by robust demand. Total prescriptions in the fourth quarter were approximately 28,400, representing growth of approximately 23% quarter-over-quarter, driven by LYBALVI's differentiated product profile and our commercial execution. This strong demand was due in large part to increased prescriber breadth and use across a broad range of patients. At the end of the fourth quarter, approximately 7,600 prescribers had written a prescription for LYBALVI since its launch, which represents an increase of approximately 27% since the end of Q3. As we have mentioned before, driving prescriber breadth continues to be a key priority for us and provides the foundation for establishing a significant brand presence and awareness in this market. More than 20,000 patients have been treated with LYBALVI through December.
Prescriptions in the quarter continue to be evenly split between schizophrenia and bipolar I patients. Approximately 45% of the prescriptions in the fourth quarter were for patients switching from olanzapine, and approximately 55% came from a variety of other branded and generic medications. This diverse source of business demonstrates that physicians are utilizing LYBALVI for a broad range of patients and not limiting its use to a particular patient phenotype. In our market research, a majority of healthcare providers surveyed report a high level of satisfaction with LYBALVI in schizophrenia and bipolar I disorder, including its efficacy and perceive that their patients are similarly satisfied with LYBALVI. Early persistency data is encouraging and consistent with other branded oral atypical antipsychotics, as we anticipated. In 2023, our focus is three-pronged: growing prescriber breadth, further enhancing the pathway to access for patients, and building awareness.
As we have mentioned before, we believe direct-to-consumer advertising will play an important role to further drive patient and caregiver awareness of LYBALVI. DTC campaigns have been shown to be highly effective in driving brand growth in many therapeutic areas, including psychiatry. Starting an effective campaign earlier in a product lifecycle provides an opportunity to capture a greater impact over the life of the product. Our digital marketing campaign is already underway, and we expect to launch the TV component of our DTC program mid-year. We believe these strategic investments will drive long-term revenue growth for LYBALVI. From a market access perspective, we are well positioned with LYBALVI for this stage of the launch. Overall, LYBALVI has been treated similar to other branded agents. In Medicare and Medicaid, we have a pathway to access for all patients.
On the commercial side, we have established a solid foundation in terms of access, and we will engage with the commercial payers again this year, now with the advantage of a year's worth of market experience and data. In the meantime, eligible patients have a pathway to access through our patient and co-pay assistance programs. We expect LYBALVI 2023 net sales in the range of $180 million–$205 million . We anticipate gross to net adjustments will remain fairly stable in the high 20% range during the first half of the year and may widen in the second half if we determine there is a benefit to enhancing the access profile for LYBALVI. Turning to the ARISTADA product family.
Net sales in the fourth quarter were $79.2 million, driven primarily by TRX growth of approximately 7% year-over-year on a months of therapy basis. We are encouraged by the return to growth in the LAI class. In 2022, prescriber breadth for the product family reached an all-time high, driven by our commercial strategy and the attributes of ARISTADA, despite some persistent challenges in the class, such as ongoing staffing shortages in treatment settings. We expect to continue to grow our prescriber breadth and depth in the coming year. For 2023, we expect ARISTADA net sales in the range of $380 million–$410 million.
This range reflects current market dynamics and our continued emphasis on ARISTADA's differentiated value proposition, including its once every two-month dosing option and the ARISTADA INITIO initiation regimen, both of which are supported by clinical data from our ALPIN study. Moving to VIVITROL. Net sales in the fourth quarter increased approximately 11% year-over-year to $102 million. Growth in VIVITROL sales continues to be driven primarily by the alcohol dependence indication, which accounted for approximately two-thirds of the VIVITROL business in the quarter. For 2023, we expect VIVITROL net sales in the range of $380 million–$410 million as we continue to advance our strategy to drive growth in the alcohol dependence indication. VIVITROL is a complex product in a complex treatment environment.
Our end of litigation with Teva is starting today. We remain confident in our position. Regardless of the outcome of that litigation, we believe that the complexities of this market and the required capabilities that we have established to support VIVITROL's commercialization will prove challenging for potential generic entrants. We remain committed to driving awareness of VIVITROL's utility and believe it will continue to have an important role to play in the treatment paradigm. LYBALVI, VIVITROL and ARISTADA represent a strong proprietary product portfolio that will serve as the cornerstone of Alkermes' top-line growth potential as a pure-play neuroscience company following the planned separation of the oncology business. This product portfolio and the operating leverage that we have built into the business provides significant opportunity to drive growth, and we look forward to updating you on our progress throughout the year.
With that, I will now turn the call over to Iain .
Great. Thank you, Todd. Hello, everyone. We finished 2022 strong and are pleased to report financial results ahead of our expectations for the year, driven by the solid performance of our proprietary products and disciplined management of our cost structure. The launch of LYBALVI was a highlight for the year and represents a significant growth opportunity for the company in the large oral antipsychotic market, leveraging our established commercial capabilities. The strength of the LYBALVI launch was an important factor in our decision to explore the separation of the oncology business, which we believe will help reveal the underlying growth and profitability of the neuroscience business.
In the next few minutes, I'll take you through the details of our 2022 results, then turn to our 2023 financial expectations and underlying assumptions for both the neuroscience and oncology businesses, and then finish with our updated long-term profitability targets. Starting with our 2022 financial performance, we generated total revenues of $1.11 billion, driven primarily by our proprietary product portfolio, which grew 24% year-over-year and now represents approximately 70% of total revenue. This growth reflects strong results from the first full year of the commercial launch of LYBALVI, as well as double-digit growth for each of VIVITROL and ARISTADA.
From a bottom line perspective, we recorded GAAP net loss of $158.3 million, compared to $48.2 million in the prior year, and non-GAAP net income of $57.9 million for the year, compared to $129.1 million in 2021. Recall that the 2021 results included 12 months of US J&J royalties, while 2022 results only included 1 month. A full year of these US royalties would have yielded approximately $200 million of incremental revenue. Now turning to VIVITROL, in 2022, we recorded net sales of $379.5 million, up 10% year-over-year, driven primarily by growth in the alcohol dependence indication.
In the fourth quarter, VIVITROL achieved net sales of $102 million, reflecting 6% growth sequentially and 11% growth year-over-year. Inventory levels were relatively stable in comparison to the end of the third quarter. During the quarter, we recorded gross to net favorability of approximately $6 million, primarily related to Medicaid prior period credits from certain states and lower Medicaid billings coming in than originally estimated. Moving on to the ARISTADA product family. For the year, ARISTADA net sales increased 10% to $302.1 million, primarily driven by underlying demand. For the fourth quarter, ARISTADA net sales were $79.2 million, up 5% sequentially and up 1% year-over-year. Gross to net adjustments were stable at 54.6%. Inventory in the channel increased slightly.
LYBALVI net sales for the first full year of its launch were $96 million. For the fourth quarter, net sales were $34.9 million, up 29% sequentially, driven by continued strong underlying demand growth. During the quarter, inventory levels increased as expected in line with demand growth, and gross to net adjustments in Q4 were relatively stable at approximately 25%, primarily reflecting the continuation of less restrictive initial commercial payer coverage. Moving on to our manufacturing and royalty business. For the year, we recorded manufacturing and royalty revenues of $332 million compared to $541.8 million in the prior year. We saw solid growth of VUMERITY, which was up 32% year-over-year, contributing $115.5 million of royalty and manufacturing revenues.
That compares to $87.4 million in the prior year. Royalties from sales of the long-acting Invega products were $115.7 million compared to $303.1 million in 2021. The decrease was driven primarily by Janssen's partial termination of the agreement related to royalties on sales of the long-acting Invega products in the United States. Arbitration proceedings related to this matter are ongoing, and last month we announced that the tribunal had issued an interim award finding that Janssen may not continue to sell the products developed under the agreement without paying royalties pursuant to.
Ladies and gentlemen, please stand by. We are experiencing technical difficulties. Our conference will resume momentarily. Once again, thank you for joining us. Please stand by. Your conference will resume momentarily. Thank you. Ladies and gentlemen, please remain on the line. Your teleconference will begin shortly. We're experiencing technical difficulties. Thank you. Please remain on the line. Your teleconference will resume momentarily. Thank you. Ladies and gentlemen, thank you for standing by. Sandy, please continue.
Okay. Sorry about that. I think we had a couple of technical issues, but we're back now. I'll pick up again where I was talking about the manufacturing and royalty business. For the year, we recorded manufacturing and royalty revenues of $332 million compared to $541.8 million in the prior year. We saw solid growth of VUMERITY, which was up 32% year-over-year, contributing $115.5 million of royalty and manufacturing revenues compared to $87.4 million in the prior year. Royalties from sales of the long-acting Invega products were $115.7 million compared to $303.1 million in 2021.
The decrease was driven primarily by Janssen's partial termination of the agreement related to royalties on sales of the long-acting Invega products in the United States. Arbitration proceedings related to this matter are ongoing, and last month we announced that the tribunal had issued an interim award finding that Janssen may not continue to sell the products developed under the agreement without paying royalties pursuant to the agreement. We'll continue to engage with Janssen and the tribunal in additional proceedings prior to the tribunal's issuance of a final award. Turning now to expenses. Total operating expenses were $1.25 billion for the year. Cost of goods sold for 2022 increased approximately $20.7 million year-over-year to $218.1 million, primarily driven by higher volumes of key manufactured products.
R&D expenses for 2022 were $393.8 million, reflecting focused investments in the nemvaleukin clinical program and our earlier stage neuroscience and oncology development programs, including the initiation of a first-in-human study of our orexin 2 receptor agonist program. This compared to R&D expenses of $406.5 million in the prior year. SG&A expenses for 2022 of $605.7 million increased $44.8 million as compared to the prior year, primarily related to investments in the launch of LYBALVI. Turning to our balance sheet, Alkermes is well positioned from a cash perspective.
We ended 2022 with approximately $740 million in cash and total investments, and with total debt outstanding of approximately $293 million, we had a positive net cash position of approximately $447 million at the end of the year. I'll shift now to our financial expectations for 2023 and the key underlying assumptions.
Our guidance for the year reflects continued expected growth of our proprietary products, focus on disciplined expense management, and investment in the strategic priorities that we believe will drive growth and value for shareholders, including continued progress with the launch of LYBALVI, advancement of our orexin 2 receptor agonist program in clinical studies, and separation of the oncology business. The financial guidance we are providing today reflects the combined neuroscience and oncology business for the full year as we work toward the planned separation, which we currently expect to complete in the second half of the year. As the year and our work progresses, precise timing of the planned separation will come more clearly into focus. Following discussion of the combined business guidance, I'll outline the oncology and separation related spend embedded within these expectations.
Our financial expectations for the year also reflect our current assumption that we will continue to receive royalty revenues related to sales of the long-acting Invega products outside the US through the end of May 2023. This is due to the three-month notice period that Janssen would be required to provide in order to terminate the agreement in these markets. We will continue to exclude from our guidance any potential royalty revenue related to sales of the long-acting Invega products in the US as arbitration proceedings with Janssen related to these royalty payments are ongoing. I want to underscore that removing these Janssen cash flows from our guidance and profitability targets is for planning purposes only and does not in any way reflect our belief in the strength of our legal position in this matter.
This approach also has the benefit of providing a clearer picture of the strength of the underlying business, driven by our proprietary products in VUMERITY and the operating leverage that we've engineered into the business. I'll now walk through the highlights of our 2023 financial expectations. The full expectations were outlined in the press release in the 8-K issued this morning. For the top line, we expect total revenues to be in the range of $1.13 billion–$1.25 billion . For our proprietary products, I'll start with LYBALVI. We currently expect LYBALVI net sales in the range of $180 million–$205 million for 2023.
This range reflects our current expectation of continued demand growth and that gross to net adjustments will remain fairly stable during the first half of the year and then could widen in the second half if we enter into any additional commercial contracts. For VIVITROL, we expect net sales in the range of $380 million–$410 million , and for ARISTADA, we expect net sales in the range of $315 million–$345 million . In terms of our operating expenses for 2023, cost of goods sold are expected to increase to a range of $230 million–$250 million , primarily driven by increased volumes of key manufactured products.
R&D expenses are expected to be in the range of $370 million–$400 million , driven by investment in the potential registration enabling studies for nemvaleukin, as well as the early clinical development for the orexin program, which is expected to yield initial proof of concept data in patients by the end of the year. SG&A expenses are expected to be in the range of $695 million–$725 million . The year-over-year increase primarily reflects strategic investments in the planned DTC campaign for LYBALVI and costs related to the separation of the oncology business. We expect GAAP net loss to be in the range of $160 million–$200 million , and we expect non-GAAP net income to be in the range of $0–$40 million .
As I mentioned, these financial expectations reflect a full year of the combined neuroscience and oncology business. At the midpoints of the provided ranges, our operating expense line items include approximately $190 million of spend related to advancing the oncology business and costs associated with the planned separation transaction and building the necessary infrastructure to support the oncology business as a standalone publicly traded company. A more detailed breakdown is available in the slides accompanying the webcast. This estimate is intended to provide a general illustrative framework for thinking about the various components of the business and may be refined as we progress through the year. The planned separation of the oncology assets is expected to enhance the profitability of the remaining neuroscience business. To reflect this improved financial profile, today we announced updated long-term profitability targets.
The new targets reflect a one-year acceleration of our previously provided targets and specifically increasing our non-GAAP net income margin targets to 25% in 2024 and 30% in 2025, and increasing our EBITDA margin targets to 20% in 2024 and 25% in 2025. For clarity, these improved profitability targets continue to assume the removal of all worldwide royalty revenues related to sales of the long-acting Invega products, as well as the successful and timely completion of the planned separation in 2023. Taking a step back, we believe separating the oncology business has many operational virtues and will also significantly enhance the financial profile of the resulting neuroscience company, which we expect will emerge with a growing top line, simplified capital allocation decision making, a streamlined cost structure, and expanding margins.
The updated and accelerated profitability targets provided today are a reflection of our commitment to driving growth and long-term profitability, and we look forward to updating you on our progress as we forge ahead. With that, I'll hand the call over to Rich.
That's great, Iain. Thank you. Before talking about what lies ahead in 2023, I wanna note the significance of 2022 as a turning point for the execution of our strategy at Alkermes. With the strong launch of LYBALVI on top of double-digit revenue growth for VIVITROL and ARISTADA, our neuroscience business is evolving as we planned. Our R&D investments are also showing promise, with nemvaleukin enrolling in registration-enabling studies in oncology and our orexin 2 receptor agonist entering and progressing in the clinic. From a financial standpoint, we continued our sharp focus on operational efficiency, disciplined expense management, and driving profitability. We managed the business with these elements in mind: commercial execution, R&D productivity, financial discipline. All were evident in 2022.
2023 is gonna be an important year, one in which we build on the accomplishments of last year and establish a new trajectory for the company. We're focused on three key operational areas. They are driving the ongoing launch of LYBALVI, advancing our orexin program in narcolepsy and other sleep disorders, and executing on the planned separation of our oncology business. I'll spend a little time on each of them, starting with LYBALVI. The strong traction of the LYBALVI launch in 2022 gives us confidence in its potential. As the first year of launch progressed, healthcare providers have noted LYBALVI's differentiated weight profile in comparison to olanzapine in their own practices.
Looking ahead, we believe LYBALVI's long-term potential in this market will be grounded in its proven clinical efficacy, which is rooted in the established efficacy of olanzapine and demonstrated in our pivotal clinical trials, along with real-world patient and healthcare provider experiences. As you heard from Todd, we have a clear focus in 23, driving the breadth of prescriber base, further enhancing the access profile, and building awareness among patients, caregivers, and healthcare providers. Major brands in this category build steadily over time, and we believe the LYBALVI DTC campaign will play a significant role in driving its growth trajectory in this disease area that is characterized by millions of patients and frequent changes in medications. We're excited about the opportunity LYBALVI represents as a new treatment option for patients, but also for its potential to drive growth at Alkermes.
The second priority is to advance ALKS 2680, our orexin 2 receptor agonist program in narcolepsy and other sleep disorders. This program represents an exciting opportunity in neuroscience, given both the strong biological relevance of the orexin pathway to narcolepsy and the significant potential market opportunity. From a scientific standpoint, there's a strong linkage between the orexin pathway and the disease. The challenge is one of molecular design. We've leveraged our chemistry capabilities and pharmacokinetic expertise to develop highly potent small molecule orexin agonists designed to capture the performance of the endogenous natural neuropeptide in affecting wakefulness and cataplexy. Potency is an essential component for efficacy and safety, but it is not enough on its own. It must be coupled with CNS penetration with a pharmacokinetic profile that promotes wakefulness during the day and sleep at night.
Based on our preclinical and modeling work, we believe that ALKS 2680 can embody these attributes in a convenient once-daily dose. We started the first-in-human study for 2680 in the fourth quarter of last year. We're moving quickly. We've now dosed several cohorts in the single ascending dose study. We are well into dose levels that our modeling indicates should be therapeutically relevant in narcolepsy. Thus far, the safety and tolerability profile in healthy volunteers has been good and consistent with what we observed in preclinical studies. We've been collecting EEG data following single doses in healthy volunteers. Are encouraged to have seen early signals of target engagement. We've cleared sufficient dose levels in the single ascending dose study to trigger the initiation of the multiple ascending dose study. Expect to begin enrolling subjects in the coming weeks.
This study design involves daily dosing of ALKS 2680 for 10 days. We also plan to initiate a Phase 1b proof-of-concept study to evaluate traditional clinical efficacy endpoints, such as maintenance of wakefulness in narcolepsy type 1, narcolepsy type 2, and idiopathic hypersomnia.
Ladies and gentlemen, please stand by. We're experiencing technical difficulties. Your conference will resume momentarily. Once again, thank you for joining us today, and your teleconference will resume momentarily. Thank you. Thank you again for joining us. Your teleconference will resume momentarily. Thank you. Thank you for joining us. The call will resume momentarily. Thank you. Ladies and gentlemen, thank you for standing by. Our teleconference will now resume.
Okay, apologies. We're having some telecom issues today. I'll pick up where I left off. I was talking about the study that's underway in our narcolepsy program. I was making the point that as we launch the Phase 1b proof-of-concept study that'll actually begin looking at the traditional clinical efficacy endpoints. And the most important one is probably Maintenance of Wakefulness, which we're gonna test in patients with narcolepsy type 1, narcolepsy type 2, and idiopathic hypersomnia, as well as in sleep-deprived healthy volunteers. Taken together, these studies are designed to generate preliminary proof of concept data by the end of the year. With a strong biological rationale and significant medical and economic potential, we believe that this program offers an opportunity to create considerable shareholder value.
We'll continue to focus on careful execution while carefully and expeditiously advancing the program, and we look forward to sharing our progress with you throughout the year. Finally, our third priority for the year is to complete the separation of the oncology business. We believe this separation, if we complete it, will unlock value and position both the oncology business and the remaining neuroscience business for growth and success as we simplify the investment thesis and capital allocation decision-making for each business. The oncology side of the business has a compelling standalone investment thesis anchored by the potential of nemvaleukin, our novel investigational engineered IL-2 variant that is a potential first-in-class cancer immunotherapy. The IL-2 pathway offers significant potential in oncology.
nemvaleukin is the most advanced IL-2 variant in development and is distinguished by the data generated in the clinic showing antitumor activity as single-agent monotherapy and in combination with checkpoint inhibitors. Our current development efforts are focused on potential registration-enabling studies in two difficult to treat tumor types. ARTISTRY-6 is evaluating nemvaleukin as monotherapy in mucosal melanoma, and ARTISTRY-7 is evaluating nemvaleukin in combination with pembrolizumab in platinum-resistant ovarian cancer. These are ongoing blinded studies, and we'll continue enrolling both this year. The new post-separation oncology company would have a pipeline of other preclinical immunotherapy programs, our engineered tumor-targeted IL-12 and engineered IL-18, both of which have been advancing preclinical development and represent attractive oncology targets.
With a late-stage asset with the potential to be a first-in-class medicine, preclinical pipeline assets, and clear developmental milestones, we believe the separation of the oncology business represents a compelling potential opportunity for oncology-focused investors. I'll give you a quick update on the status of the planned separation. While we continue to evaluate a range of options for the separation of the oncology business, spinning the oncology business into an independent, publicly traded company is our planning scenario. We have a knowledgeable team leading the separation efforts as well as an engaged board providing oversight that has deep experience and expertise in separations and other transactions. There's a tremendous amount of work underway related to tax planning, SEC and corporate governance matters, public company listing requirements, and organizational structure.
In terms of leadership for the post-separation oncology company, the recruiting process for the CEO and other leadership positions is well underway, and we're pleased with the level of interest and the caliber of the candidates coming through the process. Across the work streams, we're making progress and expect to complete the proposed separation in the second half of 23, subject to customary closing conditions, including final approval from the board of directors. Following the planned separation, we expect Alkermes to become a profitable pure-play neuroscience company. Alkermes will continue to build on our heritage of innovation and excellence in this therapeutic space with a focus on significant unmet needs within neuroscience.
With a strong top line growth, I'm sorry, driven by the growth of our proprietary products, a specialized commercial infrastructure in neuropsychiatry and addiction, and proven drug development capabilities, the standalone neuroscience business represents a significant opportunity to capture operating leverage, drive growth and profitability, and advance potential new medicines for neurological disorders. I will finish there. With a clear path forward for all aspects of the business, we enter 2023 with significant operational momentum, and we're well positioned to create value for our shareholders. With that, I'll turn it back to Sandy. Hope that we don't drop the line again, and we can run the Q&A.
All right. Thanks, Rich. Rob will open the call for Q&A now.
Thank you, Sandy. At this time, we'll be conducting a question and answer session. If you'd like to ask a question, please press star one from your telephone keypad, and a confirmation tone will indicate your line is in the question queue. You may press star two if you would like to remove your question from the queue. For participants that are using speaker equipment, it may be necessary to pick up your handset before pressing the star keys. That we may address questions for as many participants as possible, we ask you please limit yourself to one question. One moment please while we poll for questions. Thank you. Our first question today comes from the line of David Amsellem with Piper Sandler. Please proceed with your question.
Hey, thanks. So I just wanted to drill down on the longer-term margin targets. Can you talk about the balance between SG&A and R&D spend on the neuropsych business? I guess what I'm trying to better understand is, you know, how are you thinking about R&D in the context of, you know, what seems like a pretty lean infrastructure with just the orexin, you know, in the clinic? Should we assume that there's gonna be considerably more promotional investment in LYBALVI, not just this year, but continued further investment and growth in SG&A as a result in the product? Just help us frame those puts and takes, if you will. Thank you.
Long-term margin targets is really a combination of 2 things. One, you've obviously got revenue growth on the top line, and then we're looking to have as much of that incremental revenue flow down to the bottom line in order for us to be able to hit the targets. You know, that said, LYBALVI is gonna be a big driver on the top line. To make sure we maximize the opportunity for LYBALVI, we'll be continuing to invest in the DTC campaign, you know, over the next 2 years. I think we're gonna learn a lot in this 1st year as we have launched the digital campaign, and then we launch the TV campaign. We'll be able to fine-tune, maximize the effectiveness of that investment.
From an R&D perspective, you know, the model going forward is to have a leaner R&D organization, absent the oncology assets. We also realize we need to invest for the longer term. We'll be doing some work from our early discovery engine, and then also looking at potentially insourcing some programs into the pipeline as well. You know, that overall focus on profitability is a key tenet for us. It has been for the last few years, and it will continue to be so into the future.
Okay. Thank you.
Next question is from the line of Akash Tewari with Jefferies. Please proceed with your question.
Hey, thanks so much. Maybe just a few if I can. On your long-term guide, even with the spin, I wasn't getting to your guided net income targets in 2025, unless I put a LYBALVI number that's close to $500 million. Am I missing something here, or is it fair to say your internal expectations on this product have grown since last year? On your orexin program, the liver toxicity on Takeda's OX2 seemed to show up after a month of dosing. With that in mind, are you planning in your MAD healthy trial or in any of the trials that you're going to have this year to dose patients for an extended period of time? How do you feel about de-risking safety, particularly around liver toxicity as you enter into a phase IIb trial? Thanks.
On the long-term profitability targets, what I will say is, you know, we haven't provided our long-term expectation or our peak sales expectation, and we will not do so today. As I mentioned, the achievement of the profitability targets is really be driven by growth of all three of our proprietary products and the growth of VUMERITY as well, which will be a key flow-through to the bottom line for us. Obviously, as I mentioned previously, that growth in revenue flowing down to the bottom line in order to be able to achieve the targets that we set out today.
As Rich, maybe I'll take the orexin question. Our view is that the toxicity seen from other compounds are largely idiosyncratic to those particular structures rather than orexin 2 agonism per se. To the question, the objective in this year is to establish that proof of concept, target engagement, affecting the architecture of the sleep-wake cycle, and establishing dose. The best way to interrogate the longer term toxicity potential is by interrogating at the appropriate dose. Now, know that in the design feature going into the program was to maximize or optimize around potency. Potency in and of itself being a really clear design objective to minimize the potential for off-target drug-induced liver injury.
You know, you'll never fully answer to that question until you get longer exposures, as you indicate, at the relevant doses in the patient population of interest.
Thank you. The next question is from the line of Umer Raffat with Evercore ISI. Please proceed with your question.
Hi, guys. Thanks for taking my question. First, maybe perhaps on LYBALVI. I appreciate all the color on launch metrics. Something I've been thinking about is the number of prescriptions per prescriber appears to be fairly stable, and I would have thought that over time, there's more prescriptions per prescriber just given the refills and new adds. Just trying to understand if the TRX growth really is being driven more by the new prescribers signing on. Would appreciate any color on that. Secondly, Rich, could you clarify on the orexin trial? Is it the SAD cohorts that you've seen data on, or are you also seeing the Part II MAD? Also, if you could speak to how many formulations are in the trial and if there's a notable difference between these formulations for the orexin. Thank you.
Yeah, I'll start off with kind of the dynamics we're seeing with the prescriber base. We're really encouraged by what we're seeing overall. It's consistent breadth of prescribing on a month-over-month and quarter-over-quarter basis. Your question is right. Overall, the breadth of prescribing right now, the depth of prescribing is relatively stable. That's actually an encouraging sign because our prescriber breadth continues to grow. We actually see a lot of the expansion right now coming from new prescribers as we bring new prescribers on board.
Launch to date, we're encouraged that approximately 7,400 prescribers have written the product and, you know, our aspiration is that's gonna continue to grow consecutively over the next couple of quarters as we continue to advance the launch and as Iain said earlier, as we light off the DTC component of our campaign at mid-year this year.
Over to Rich. You know, just to echo what Todd is saying. Our experience is when physicians try LYBALVI, they like it. Driving breadth is, in our view, operationally an essential prerequisite to driving depth. I think we're excited about the way the breadth is maturing. I had a hunch you'd ask a question about the orexin. What I'd say is that the data we're seeing right now is from the SAD cohort, the single ascending dose. This is incredibly informative. First phase of the development program because we're learning about tolerability, obviously, at ascending doses. We're seeing PK and how that PK tracks back to our modeling, which appears to be quite high fidelity at this point.
We're also, from purely translational medicine point of view, looking at quantitative EEG in healthy volunteers, non-sleep deprived, following a single dose. That's where we're just beginning now to see evidence that is consistent with the idea of target engagements. We're excited about that. The MAD cohorts will light off very soon now with ethics approval and operational go on the MAD. That should start up in the next few weeks, followed by the Phase 1b, which we'll be looking at in patients.
Thank you.
Thanks. The next question.
Yes, next question is coming from the line of Chris Shibutani with Goldman Sachs. Please proceed with your question.
Great. Thank you very much. Two questions. One, you talked about, perhaps enhancing the access profile for midyear, and how that might impact the gross to net trajectory. Could you just elaborate a little bit further about, you know, what you'll base that thinking on? In terms of the orexin agonists there, can you at this point, I know we're still very early in clinical development, talk about what you see as potentially the opportunity from a competitive positioning standpoint of how to differentiate? I've heard a lot of potency in your vocabulary. Is that really the emphasis? Ultimately, what kind of profile do you, sort of aspire to?
Yeah, I'll start off with the market access question. As we said in the prepared remarks, our expectation is that gross to net is gonna be relatively stable over the first half of the year, and it could evolve in the second half of the year. We're in constant contact with commercial payers right now in discussions with them. I think the really the way to think about this is that market access coverage in the category is not stagnant. It will continue to evolve over time. This is really a market that is really categorized by navigating step-throughs, PAs, medical exceptions, and all the work that we've done with HCPs, and this category tells us that they are well-versed in this area, and they can actually manage the dynamic.
We talk a lot about just providing a pathway to access. That's gonna be a combination and a mixture of contracting plus all the programs we have to support patient access. For LYBALVI right now, we believe we're really well-positioned. The vast majority of patients have a pathway to access. We're seeing good utilization across all of our market access programs, our PA programs, our copay programs, and we are having these ongoing discussions with payers. Right now, if we determine that we need to enhance the position, we'll do so and we'll look at that in the second half of the year, but that wouldn't happen without really a strategic investment or us strategically looking to see if we do need to enhance that position.
Chris, on the orexin stuff, I'm glad you asked the question because potency is a feature, but it's not necessarily about the benefit. What is the benefit of potency? The way we see these different compounds evolving in the clinic is that there's a number of different optimization parameters in this design of this molecule. My longstanding belief has been that these molecules are all gonna be quite different. I don't think they're all gonna be the same. Even if you stipulate if they engage the receptor, they might have the same effect on the sleep-wake cycle, they could be very, very different along several parameters. Number one is safety. We've already seen drug-induced liver injury from one construct that may or may not be recapitulated in others.
Number two is the on-target toxicity or AE that you'd be focused on are cardiovascular changes, blood pressure and heart rate. We think these may be different not just because of potency, but also because of PK. PK is also entirely relevant with respect to another point that these could differentiate, which is on the presence or absence of insomnia if your waveform is too extended and you don't allow people to return back to baseline before it's time to go to bed or if it's too brief and they don't have an extended period of wakefulness.
There's a number of different And I must say, from the very beginning of this program, we've been seeking using the animal work and other modeling work to try to optimize 2680 to be sensitive to each of these different parameters.
Thank you.
Our next question is from the line of Paul Matteis with Stifel. Please proceed with your question.
Thanks so much for taking my questions. I wanted to ask another just question about the profitability targets. Congrats on pulling those in. More specifically, how much is that pull-in driven by the oncology spin? Are there any other kind of factors, either additional cost discipline or again, change in revenue expectations that are embedded in that? Just on the orexin POC data later this year, could you just share a little bit more granularity on what we should expect? Like, how many patients on drug, placebo, you know, things like duration of treatment, things like that I think will help us understand how de-risking these data are. Thank you.
Okay, Paul, I'll take the profitability question. The spin of the oncology assets, obviously that brings down the R&D spend quite significantly. Roundabout, if you look at the little table we provided within the slides, there's about $145 million at the midpoint of ongoing oncology costs that would come out of the P&L. I think at the same time, as you see what we're doing in 2023, investing in the continued launch of LYBALVI with the DTC campaign. This year we're gonna have a full year of digital and potentially half a year of TV. You could see some incremental investments for DTC there within the sales and marketing line. Again, the ability to hit these revised targets is really gonna be predicated on revenue growth on the top line with flow down to the bottom line.
That continued focus on cost management is really gonna help us in achieving the profitability targets one year earlier than we previously anticipated.
Paul, it's Rich. The sequencing of the 2023 clinical work with orexin is very deliberate. I mentioned to Umar before, the SAD progressing into the MAD as you clear doses, particularly as you start getting into what we model to be therapeutically relevant concentrations. MAD provides 10 days of exposure, gives us PK on a steady state basis, as well as tolerability and safety with additional EEG information. Move into the 1B. The 1B will be circa 40 or 50 patients, I would say, with representation across NT1, NT2, idiopathic hypersomnia, as well as sleep-deprived individuals.
You'll get a sampling across each of those different phenotypes or disease categories, which should be enough to see whether you're having effect on the architecture of sleep, against the primary endpoint that one cares about for registration, which is this Maintenance of Wakefulness Test, which is a fairly reliable, marker for the activity of these drugs in this indication.
Okay, thanks. What about at year-end, Rich, just for, like, how much data? Not 150 patients.
The only reason I'm gonna be a little bit soft on that is because we clear ethics approval at each different stage. Depending on the timing of the ethics approval and then the subsequent enrollment. The healthy volunteers, we have a pretty good idea on because, you know, they're healthy volunteers in Phase 1 sites. As we start moving into NT1, NT2, IH, and that. We'll give you a little bit more, but I expect, I mean, our planning case is to have information in at least the NT1s this year. We'll see. We'll update. We'll go as fast as we can, obviously, but we'll see as we move through these various logistical hurdles.
Okay. Understood. Thanks so much.
You're welcome.
Our next question?
And, you know, I didn't answer-
Oh, sorry.
I did answer a piece of Umer's question, which was about formulation. There's one formulation in the clinic.
Thank you.
Different doses, one formulation.
The next question is from the line of Uy Ear with Mizuho. Please proceed with your question.
Hey, guys. Thanks for taking my question. I guess my first question is, you know, the guidance, it is the start of the year, and it seems wide. Just wondering what would it take to sort of narrow it? Secondly, could you provide us with some color on the gross and assumption for VIVITROL and ARISTADA in the guidance? I might have missed it. Thanks.
I'll take the last one first. The VIVITROL gross to net, we expect that fiscal year 2022 ended with a 50% gross to net. We originally thought it was gonna be around 52%, but we did see some favorability on the Medicaid side of the business as we went through the year. We don't anticipate necessarily seeing that favorability come through in 2023. I'd anticipate that you'd see an increase in the gross to net back up towards that 52% level. The gross to net for ARISTADA has been remarkably stable, I would say, over the last couple of years. You would expect that kind of level of gross to net to continue into the future.
Then your general question around wide guidance, as you say, it's early in the year, so there's lots of puts and takes as we go through the year that could impact the business. You know, we've done our best estimate at trying to put those together. I mean, we could go down line by line. I don't think we have time to do that. You know, looking at VIVITROL, for example, the growth in alcohol dependence, and then see what happens on the opioid side of the business. ARISTADA is very much dependent upon market growth, and we have certain assumptions built in there. Market growth could be different to what we're anticipating. LYBALVI is still in the launch phase. We've got a lot going on with regard to LYBALVI and the DTC campaign, for example.
Those are just a few examples of some of the things, certainly on the revenue side. Obviously, as we go through the year, what we typically do is we try and narrow those ranges down as we experience things throughout the year.
Thank you.
Our next question is from the line of Jason Gerberry with Bank of America. Please proceed with your question.
Hey, guys. Thanks for taking my questions. Just wanted to ask a question about the LYBALVI payer mix and gross to net specifically. You know, it seems like your gross to nets are pretty low, you know, it seems like you're not really contracted much on the commercial side, but yet you're not expecting sort of the volatility we see typically in, like, year 1, 2 for drugs that are heavily commercially insured. Just wondering if you can kind of speak to the payer mix broadly between the two indications that you have there. Just a quick follow-up question just on the VIVITROL patent case. I think it's 1 single patent in dispute, so wondering if you're expecting a pretty quick turnaround time on a ruling from the judge there. Thanks.
Yeah, I'll start off with the payer mix as well. It's a good observation. Right now, overall, what we're seeing with what we saw last year, what we saw in the fourth quarter, is we didn't see as much exposure with our overall gross to net and the rebates that we had to pay. You know, when we launched the product, we put a number of programs into place that are
Our PA program, our co-pay program, we're actually seeing really good utilization. For example, north of about 70% of all of our prior authorizations are approved, which is very consistent with the branded category. I think also what we're seeing is we're seeing the real leverage in the dual indication, schizophrenia and bipolar. Schizophrenia, the mix, typically with schizophrenia patients is a higher mix within Medicare and Medicaid. Within bipolar, you actually see a higher mix of commercial and Medicaid. We're getting a healthy mix of both of those right now. Overall, as time settles out, we believe that LYBALVI will be very consistent with the category, which is basically about a third for commercial, a third for Medicaid, and a third for Medicare.
On the ANDA litigation, while you're correct, there's a single patent, there's a series of arguments that underneath that patent that are fairly nuanced and will be discussed during the trial. I won't speculate how fast or slow the judge will work. Our assumption is that there'd be some type of decision in the Q2 timeframe.
Got it. Thanks.
You're welcome.
Our next question comes from the line of Jessica Fye with J.P. Morgan. Please proceed with your question.
Hey, guys. Good morning. Thanks for taking my questions. When we think about the guidance for 2023 SG&A up around $100 million at the midpoint year-over-year, I imagine much of this is DTC for LYBALVI, but can you quantify that? How should we think about the annualized DTC cost for LYBALVI as we think ahead to 2024, for example? Sticking with LYBALVI, but on gross to nets, I wanna make sure I understand what's embedded as it relates to your LYBALVI sales guidance for 23. I think you mentioned high 20s in the first half, and that may widen depending on if you do additional contracting. What's baked into the revenue guide in terms of widening in the back half, if anything?
Would that be upside to sales guidance if you opt to not go that route?
Okay, Jessica. Thanks for the questions. I'll take a go at those. For 2023, within SG&A, you'll see there's about $75 million, $80 million of incremental sales and marketing spend, and the majority of that is focused on the DTC campaign. That would be for a full year of digital and half a year of TV. If you think about the further years out, 2024 and 2025, if there was a full year of both TV and digital, then yeah, there would be an increase in SG&A proportionately. Also within the G&A, I think I did mention, and it's illustrated a little bit in the slide that we have in the tables. A lot of the one-time type separation costs associated with separating out the oncology business are included within the SG&A line.
There's about $45 million of costs in total between building out the infrastructure for the standalone entity and those one-time costs. That looks like G&A is increasing by more than it will. Obviously, with the neuroscience business on a standalone basis, those costs will no longer be part of the business. From a gross to net perspective for LYBALVI, as Todd mentioned, high 20s for the first half of the year. The net sales range we gave today of $180 million–$205 million really encapsulates a range of gross to net possibilities that we could see in the second half. We're not being specific today. That'll become more into light as we enter into any potential negotiations, and we'll be able to provide more detail as we go through the year.
Great. Thank you.
Thank you. Our next question is from the line of Marc Goodman with SVB. Please proceed with your question.
Morning. Rich, could you talk about what's going on behind the scenes with trying to build a deeper pipeline on the CNS side? Do you think in a year from now there'll be more products there? I guess the question is partly how aggressive you're gonna be on the BD side and then also what's happening in discovery. I know you don't wanna disclose anything, but maybe you can just talk about it if something will be disclosed over the next year or so. Thanks.
Yeah. Morning, Marc. It's probably too early to make a call on that other than when you think about the neuroscience company spun, it's gonna have orexin moving aggressively in the clinic. The pipeline behind that, we've not given you guys any visibility into. In part because some of it, as you indicated, is not ready, but also because we'll need to populate it with some additional candidates. The R&D and profitability guidance that Iain has mentioned accommodates the idea of expanding the pipeline, but not in a dramatic fashion. I mean, we're not gonna go out on a spending spree because we're managing business to hit those profitability targets.
As the revenue line grows, if we maintain on a ratio basis an R&D line that's in line with what our peer companies would do, it accommodates the expansion of R&D. Of course, the major toggle is what happens with the orexin program. If that continues to roll, that's gonna become a really important feature of the pipeline.
Well, I guess what I'm getting at is that, you know, the BD side is really up to you, right? I suppose, you know, how aggressive you wanna be. I guess I'm just curious how aggressive what does it look like out there? you know, we know what has happened to the biotech sector over the past couple of years. It just seems like a good time for you to be, you know, building up the pipeline, taking advantage of those opportunities.
Yeah, I think that, I think that you're right. I think that there's We went through a period of time there really wasn't much out there that we were attracted in now. I think that the group is active now, but that happens on such an episodic basis, you know, when the stars align and you find something that meets the criteria from a scientific market as well as intellectual property perspective. It's hard to give you guys any guidance on the timing and sequencing of that other than to know that it's a priority.
Okay, thanks.
Our next question is from the line of Douglas Tsao with H.C. Wainwright. Please proceed with your question. Mr. So, are you there for a question?
Sorry about that. Thanks for taking the questions. Just as a follow-up on LYBALVI and the comments in terms of the gross to net, just curious if you can just walk through how you're thinking about the decision whether to contract more in the second half of the year that would lead to a sort of expansion of the gross to net and what you would necessarily get for that from an access standpoint.
Yeah, absolutely. We're watching this very closely overall. We look at it a couple different ways. We're actually looking at the, you know, at the TRXs and the contribution from each of the channels. We actually see a healthy portion of prescriptions, as I said earlier in my prepared remarks on bipolar and schizophrenia, but we also see a healthy amount of prescriptions that are flowing through with commercial, with Medicaid and Medicare. We're watching that really closely. Those are discussions that we also then have with commercial payers. One of the decision points that we're thinking about is, does our access profile right now support the aspiration that we have, and if we need to enhance it in any way.
Those are discussions that we had last year, and we'll continue to have those this year. We think that LYBALVI is very well-positioned right now within market access because we are seeing the prescriptions flow through. We do a fair amount of market research with providers as well. Overall in this category, they think in general that most of the branded agents have a similar profile. There's always step edits, prior authorizations, medical exceptions. That goes into our decision point as well too. Overall, right now, we think we're really well-positioned.
Okay, great. Thank you very much.
Thank you. Our final question is from the line of Brandon Folkes with Cantor Fitzgerald. Please proceed with your question.
Hi, thanks for taking my question. I just wanna come back to the neuroscience SG&A spend. Unlike Bob, given the breadth of prescribing is driving growth currently, how do you think about your head count infrastructure and the commercial operation in 2023 and maybe embedded in those 2024 and 2025 profitability targets? Thank you.
Yeah. I think we've built the infrastructure. Initially, we built it for VIVITROL, then we were able to start leveraging it with ARISTADA. We now have 3 products that are supported by the commercial infrastructure. I think the infrastructure that we have today is gonna support growth for all 3 products into the future without us needing to spend, you know, additional money. I think the incremental investments on the SG&A side or certainly on the sales and marketing side, are really gonna be around this DTC campaign, both in this year and, you know, in the next 2 years. As I said, the idea between the DTC campaign is to grow or move that revenue line up.
You know, assuming we see that, we will continue to invest in DTC , but we're gonna learn a lot as we get into the program, and we'll be able to adjust that investment as we deem appropriate.
Great. Thank you very much.
Thank you.
Thanks, Brandon.
Please go ahead, Sandy.
All right. Thanks everyone for joining us on the call today. Apologies for the technical difficulties and bearing with us. We'll be available all day if you need us. Thank you.
This will conclude today's conference. You may disconnect your lines at this time. Thank you for your participation.
